conspicuoiisness and distinctness of tints has been encour- 
aged and developed, as well as divergence of form, size, 
and arrangement evolved to the same end, viz., greater 
attractiveness. Man himself came in at a much later 
period as a selective factor, and has enormously increased 
the brilliancy of many flowers; but it is abundantly 
obvious that a host of magnificently colored blooms of 
purely natural origin have been independent of his aid, 
when we consider some of the tropical passion flowers, 
Gloriosa superb a, Tacsonias, and so on. — From an article 
by Charles T. Druery in Indian Planting- and Gardening, 
Wanted. — Short notes of interest to the general bot- 
anist are always in demand for this department. Our 
readers are invited to make this the place of publication 
for their botanical items. 
Plants of the North west.— Last summer a party of 
botanists visited the Selkirk and Rocky Mountains in Brit- 
ish America for the purpose of collecting the plants of that 
region. Herbarium specimens of these are now for sale 
and may be obtained of Edw. B. Heacock, Wyncote, Pa. 
Pedicularis Species Wanted.— A French botanist, 
Mr. G. Bonati, of Lure, Department of Haute-Saone, is 
desirous of obtaining good specimens of American Pedi- 
cularis, being at work on a monograph of the genus. He 
offers to send in exchange plants from France and Switzer- 
land of which he has an extensive collection. Mr. Henry 
Dantun, of Cherry Hill, New Jersey, will be glad to receive 
offers and requests for exchanges, which he will duly 
transmit to Mr. Bonati. Readers of this journal will 
doubtless be glad of the opportunity to assist in the 
enterprise. The species of the far North, West and South 
are most desired.
